I run 89 octane due to making a mistake one time and put in 2/3s regular and 1/3 premium. Since I don't get pinging or anything, I stick with it.
Worst mileage I ever got was 15 mpg which was mostly a bunch of short trips that barely warmed up the engine, nowdays if I'm doing a drive like that I just don't take the 8, not worth it to put that kind of wear on the seals when the drive isn't going to be fun anyway. Best I've gotten is probably 24 mpg, I got 290 miles out of that tank driving mostly freeway with some slow bumper to bumper crap in LA.
If you're going around town and you can control your foot, I've found it's very easy to cut your gas consumption in half by short shifting, it's a very noticeable change. That said I have a hard time doing it since the saturn I drive daily is a gutless machine and having the power of the rotary on tap makes me smile when I gun the sumbitch.
Gas mileage is going to climb a bit now that it's summer, warmer/less dense air makes the computer compensate by using less fuel per power stroke, you'll lose power but it still helps a bit.
Regular WILL net you more mpgs because it tends to burn faster than premium, so there is a better chance that you're burning more of your fuel charge if it's regular. It also burns colder than premium, so unless you're flogging it, regular is going to keep the engine cooler. All that saving is not worth a damn tho if you get detonation.
If the detonation is sufficiently powerful then you can dent the face of your rotors or blow out your apex seal. A piston engine that falls victim to detonation can snap a rod, and that means it will probably shred itself. A blown seal or dented rotor won't tear your engine to pieces unless the blown seal chews up the entire housing (which can happen), but you still need a rebuild as much as the piston engine does. And it's easier to damage the rotors or seals than it is to blow a rod afaik.
However even if you have damage from detonation, a rotary is still capable of putting out some form of power, something a piston engine can't do.
